You have to convert 77 degrees Fahrenheit to degrees Celsius.
The equation to convert degrees Celsius to degrees Fahrenheit is given:
[tex]F=\frac{9}{5}C+32[/tex]First, you have to write the equation for C:
- Pass 32 to the left side by applying the opposite operation to both sides of the equal sign:
[tex]\begin{gathered} F=\frac{9}{5}C+32 \\ F-32=\frac{9}{5}C+32-32 \\ F-32=\frac{9}{5}C \end{gathered}[/tex]- Multiply both sides of the equation by the reciprocal of 9/5
[tex]\begin{gathered} (F-32)\frac{5}{9}=\frac{5}{9}*\frac{9}{5}C \\ \frac{5}{9}(F-32)=C \end{gathered}[/tex]Now that you have determined an expression to convert degrees Fahrenheit to Celsius degrees, you can convert 77ºF to Celsius, replace the equation with F=77 and solve for C:
[tex]\begin{gathered} C=\frac{5}{9}(F-32) \\ C=\frac{5}{9}(77-32) \\ C=\frac{5}{9}*45 \\ C=25 \end{gathered}[/tex]77 degrees Fahrenheit is equal to 25 degrees Celsius.
